CaaS Engine是华为依托畅连业务通信能力，面向应用开发者提供的开放接口，CaaS Engine基于开发者应用自身的联系人（好友）等社交体系，可以帮助开发者快速实现应用内音视频通话服务。
在这个Codelab中，你将创建Demo Project，并将CaaS Engine的SDK集成到Demo Project中，以及完成CaaS Engine服务的整体流程搭建。
集成CaaS Engine能力，需要完成以下准备工作：
向项目中的build.gradle中配置仓库：
buildscript {
repositories {
google()
jcenter()
maven {url 'https://developer.huawei.com/repo/'}
}
}
allprojects {
repositories {
maven {url 'https://developer.huawei.com/repo/'}
google()
jcenter()
}
}
在工程APP目录中的build.gradle中添加如下依赖：
repositories {
flatDir {
dirs 'libs'
}
}
dependencies {
implementation group: 'com.huawei.caaskit', name: 'caaskitlite', version: '1.0.1.400', ext: 'aar'
}
点击同步工程按钮，进行工程同步，如下图所示：
同步成功后，如下图所示：
在自身应用AndroidManifest.xml中添加开发者联盟创建应用时生成的appid信息，name为"com.huawei.hms.client.appid"，value为"appid=*"，*用自己注册的appid。权限申请，请依照《开发指南》中"开发准备"的详细说明来完成。
CaasKitHelper.java
public class CaasKitHelper {
private static final String TAG = "CaasKitHelper";
